I UNITE ,STA':[ ES PATENT oFFro PIPE RIG COUPLING.

'0 all whom it may concern:

Be it known that W8, I IARRY J. GIBNEY and JOHN A. VVoLFu, citizens of the United Our invention relates to improvements in pipe rig couplings for the legs, braces and girts of pipe; derricks, in which the steel bowl or .sleeveof the coupling is reinforced by a solid steel pin or shaft, less in diameter than the opening of the bowl, said pin being cast as part of the'coupling and extending lengthwise beyond the bowl several inches; and the objects of our improvements are, first, to secure firmness, strength and stability in a pipe derrick structure by the insertion of the solid steel pins of the coupling several inches into the pipe legs ofthe derrick andthe resting of the ends of the pipe legs in the bowl of the coupling, thus holding-,the structure firmly in place by its own weight; second, to hold the pipe structure more firmly in place by the use of a bolt hole in the side of the bowl of the coupling at its center through which bolts are run to bolt the braces and girts thereto. lVe attain these objects by the device illustrated in the accompanying drawing in which- Figure 1 is a perspective view of the coupling as it appears with portions of a tubular derrick leg, or pipe-rig structure, connected thereby, showing the ends of the girts of said structure connected thereto;

Fig. 2 a perspective view of the coupling by itself, aportion of one side of the central part being broken away to illustrate the annular seat or recess, for the end of pipe section, more clearly; Fig. 3 a central longitudinal section as through Fig. l on a line intersecting the bolts for the attach- ,m'ent of the girts E thereto; and Fig. t an end elevation of the coupling separately.

Similar letters refer to similar parts 1 throughout the several view A is the bowl or sleeve of the coupling with which the shaft or pin B is castandof which it is a-part; C are the seats of the bowl in which the pipe legs such as B rest on either side; D is the bolthole passin through the bowl from side to side and "are the bolts by means of which the guts and braces of the derrick are bolted on to the coupling. In using the Specification of Letters Patent. Patented Aug 13, Application filed June 24, 19 11. Serial No. 635,228. A

coupling, which may be of varying sizes according to the size of pipe used, in the course of rigging up or constructing'a pipederrick, the pipe legs .are placed in the seats C of the bowl, the lower pin of the coupling extending downward into,t'h eilower pipe leg. and the upper pin of the I I l coupling extending upward into the upper pipe legs The pin of the coupling ,should" 5 be of the same diameter as the opening of the pipe leg, thereby making a close tit and making it necessary for the pin to be driven into the end of the pipe leg. The

weight of the pipe legs resting upon the,

several couplings thus reinforced by the .solid steel pin or shaft cast with it, pro

simplicity of this coupling with the easy method of incorporating it in the structure of the pipe derrick is vastly superior to all other so called couplings or sleeves, not only in stability but as a labor saving device. Should the bowl ot the coupling become broken or chipped the pins extending into the legs of the derrick will in themselves prevent the legs from collapsing or telescoping, thus wrecking the derrick. as is now the tendency in the case of all other so called couplings or sleeves in use.

lVc are aware that prior to our invention, pipe rig couplings or sleeves have been made and used, we therefore do not claim such appliance broadly, but,

\Ve claim:

1. In a coupling device for the joints ,of derricks and similar pipe-rig structurcs an' integral coupling member having two oopo sitely projecting solid cylindrical pins operable to fit tightly the respective bores of two tubular sections to be connected, the

central body portion of said member; being of a larger diameter than the pipe sections and formed with an annular recess on each end surrounding the bases of the projecting pins and operable to engage the ends of the tubular .sections to be connected, said central body portion being solid having a perforation extending therethrough transsubstantially as described. i 2. In a coupling device versely and adapted to receive a bolt to attach other parts of the structure thereto,

for derricks and I similarpipe-rig structures,- a coupling mem- 15 body portion havinga transverse bolt hole ber having a central body portion with solid. 1 pins integral therewith and projecting each extending therethrough and said central portion having an annular recess formed the ends of the structure sections, said coupling member being adapted to be disposed vertically and to be maintained in engagement with the structure sections by the- Weight of said member and saidsections,

substantially as described.
